Abstract：According to lots of actual measured rolling data of aluminum alloy from one factory of aluminum hot tandem rolling, the deformation resistance model by least squares support vector machine reversed modeling method is got.Meanwhile, Bacteria Foraging Optimization algorithm was applied to optimize the parameters of LSSVM model to improve the accuracy.Compared with the traditional deformation resistance model,the results show that the deformation resistance model by reverse modeling is more accurate.
